Long distance voyaging among the Pacific Islands
An international team of researchers has used geochemical fingerprinting to reconstruct long-distance voyages between central and western Pacific Islands during the last millennium A.D.
Colorado’s spicy ancient history of chili peppers
Recently identified chili pepper fossils from Boulder and Denver museums challenge millions of years of global tomato evolutionary history. Now, that's some spicy science!
360-million-year-old Irish fossil provides oldest evidence of plant self-defense in wood
Scientists have discovered the oldest evidence of plant self-defense in wood in a 360-million-year-old fossil from south-eastern Ireland. Plants can protect their wood from infection and water loss by forming special structures called 'tyloses'. These prevent bacterial and fungal pathogens from getting into the heartwood of living trees and damaging...
Greener batteries
Our modern rechargeable batteries, such as lithium-ion batteries, are anything but sustainable. One alternative is organic batteries with redox-organic electrode materials (OEMs), which can be synthesized from natural 'green' materials. A team has now introduced a new OEM for aqueous organic high-capacity batteries that can be easily and cheaply recycled.
Ridgecrest faults increasingly sensitive to solid Earth tides before earthquakes
Faults in the Ridgecrest, California area were very sensitive to solid earth tidal stresses in the year and a half before the July 2019 Ridgecrest earthquake sequence.
Wearable Patch Can Painlessly Deliver Drugs Through the Skin
The skin is an appealing route for drug delivery because it allows drugs to go directly to the site where they’re needed, which could be useful for wound healing, pain relief, or other medical and cosmetic applications. However, delivering drugs through the skin is difficult because the tough outer layer...
Perovskite Solar Cells Protecting the Earth
Last summer, metropolitan areas of Korea including Seoul were hit by an unprecedented heavy rainfall, which inundated various locations.
Arctic Ice Algae Heavily Contaminated With Microplastics
The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater.
Reality Checks on Carbon Dioxide Removal, Marine Heatwaves From UH Scientists
Over the past two hundred years, the ocean and atmosphere have been accumulating massive amounts of carbon dioxide as factories, automobiles, airplanes, and more churn out the powerful greenhouse gas.
